The core idea of the invention is to provide a method, a device, equipment and a storage medium for practicing the calculation questions online, which can realize the online practice of the calculation questions on electronic equipment.

The electronic device may be a personal computer, a mobile terminal, and the like, and the mobile terminal may be a hardware device having various operating systems, such as a mobile phone and a tablet computer.
To achieve the above-mentioned idea, the present invention provides a method for practicing on-line calculation questions, referring to fig. 1, which schematically shows a flowchart of the method for practicing on-line calculation questions provided by an embodiment of the present invention, as shown in fig. 1, the method for practicing on-line calculation questions provided by the present invention includes the following steps:
s101: and providing calculation questions.
In this step, the computational questions may be provided by randomly generating the computational questions or randomly extracting the computational questions from a question library.
S102: and providing an operation interface, wherein the calculation questions are displayed on the operation interface, and the operation interface is provided with a draft area for a user to write a draft and an answer area for the user to write answers.
Thus, by setting the draft area, the user can perform calculation in the draft area when he/she answers a complicated calculation, for example, a calculation of a type such as multiplication or division of a plurality of digits or four arithmetic operations of a plurality of digits, thereby facilitating the user to answer the calculation.
Referring to fig. 2, a schematic diagram of an operation interface according to an embodiment of the present invention is schematically shown, as shown in fig. 2, an answer area 111 and a draft area 112 are provided on the operation interface, in this embodiment, the answer area 111 may be a dashed box, the answer area 111 is disposed below a calculation question, and a user may input an answer to the calculation question in the answer area 111.
Alternatively, the draft area 112 may be all areas of the operation interface except the answer area 111, that is, the user may write a draft in all areas except the answer area 111.
S103: and receiving an operation of inputting an answer of the computational question by a user.
Optionally, during the operation of receiving the user input of the answer to the computational question, the method further includes: recording the pause time of the user in answering in the answering area; and judging whether the pause time is greater than a preset threshold value or not according to the preset threshold value, and if so, judging that the user finishes answering. At this time, the receiving of the operation of inputting the answer to the calculation question by the user is completed, and the next step is started to be executed.
Optionally, the method further includes: and receiving an operation of inputting the draft of the calculation question by the user.
When a user calculates a more complex calculation question, the user writes a draft in a draft area and obtains a final answer according to the draft, so that the user can input the draft of the calculation question before receiving the operation of inputting the answer of the calculation question.
Preferably, after receiving an operation of inputting a draft and an answer of the computational topic by a user, the method further comprises: and the screenshot saves an operation interface for inputting the draft and the answer of the calculation question by the user. Therefore, the user can conveniently answer the questions continuously by storing the user input drafts and the operation interfaces of the answers through screenshot, and the input answers and the results of whether the drafts are correct or not are acquired after a certain amount of calculation questions are finished.
S104: identifying the answer input by the user.
After the answer of the current computational problem is judged to be completed by the user, the answer input by the user can be identified through the function of handwriting character identification of a common screen, and the identified answer is stored. In addition, the answer input by the user can be recognized through a pre-trained character recognition model. The answer input by the user can be a printed font or a handwritten font. In this embodiment, a pre-trained first character recognition model may be used to recognize a print font, and a pre-trained second character recognition model may be used to recognize a handwriting font, where the first character recognition model and the second character recognition model are both neural network models. Further, the neural network model is a convolutional neural network model or a residual error network model. The convolutional neural network model is a deep feedforward neural network, and scans answers input by a user by utilizing a convolutional kernel, extracts features to be identified in the answers input by the user, and further identifies the features in the answers input by the user. Compared with other recognition models, the convolutional neural network model has higher recognition accuracy and recognition efficiency. Compared with a convolutional neural network model, the residual network model has more identical mapping layers, and the phenomenon that the accuracy is saturated and even reduced due to the convolutional neural network along with the increase of the network depth (the number of stacked layers in the network) can be avoided. The identity mapping function of the identity mapping layer in the residual network model needs to satisfy: the sum of the identity mapping function and the input of the residual network model is equal to the output of the residual network model. After the identity mapping is introduced, the change of the residual error network model to the output is more obvious, so that the identification accuracy and the identification efficiency can be greatly improved.
In this embodiment, the answer for recognizing the user input may specifically be an answer on the operation interface saved in the screenshot. In the step of recognizing the answer input by the user, a pre-trained region recognition model may be used to recognize the screenshot of the operation interface to recognize the operation interface region, where the region recognition model may be a model based on a deep convolutional neural network. And extracting a two-dimensional characteristic vector from the screenshot of the operation interface by using a trained region identification model, generating anchor points with different shapes in each grid of the two-dimensional characteristic vector, marking the identified operation interface region by using a marking frame, and performing regression processing on the marking frame and the generated anchor points so that the marking frame is closer to the actual position of the operation interface region.
After the operation interface area is identified, the character content in the operation interface area can be identified by using the character identification model, during identification, each component in the operation interface area is marked firstly, the component can comprise a calculation question (title), a draft and an answer, and then the character content of the calculation question (title), the draft and the answer can be identified through the character identification model. The character recognition model can be established based on a hole convolution and an attention model, specifically, feature extraction can be performed on a marking frame corresponding to a calculation question (title), a draft and an answer by using the hole convolution, and then the extracted features are decoded into characters by the attention model. Referring to fig. 2, as shown in fig. 2, a calculation question (title) of "16-9 + 5" and an answer of "12" can be recognized through the region recognition model and the character recognition model.
S105: and correcting the answer input by the user according to the standard answer of the calculation question.
The standard answers can be obtained by calculation of a calculation engine or by obtaining from a question bank, so that the answers input by the user can be modified according to the standard answers of the calculation questions, and whether the answers input by the user are correct or not can be judged.
Preferably, if the answer input by the user is not consistent with the standard answer, that is, the result of the correction is that the answer input by the user is wrong, the method further includes: and identifying the draft input by the user and judging whether each calculation step of the draft input by the user is correct or not, and if the calculation step has an error, marking out the calculation step. Therefore, the user can be helped to quickly find out which calculation step has errors in the process of calculating the answers by identifying the drafts input by the user.
Similar to the answer recognition method, the drafts input by the user can be recognized through a common function of screen handwriting character recognition, the recognized drafts are stored, and the drafts input by the user can be recognized through a pre-trained character recognition model. The draft input by the user can be a printing font or a handwriting font, so that the printing font can be recognized by adopting a pre-trained first character recognition model, the handwriting font can be recognized by adopting a pre-trained second character recognition model, and the first character recognition model and the second character recognition model are both neural network models.
Correspondingly, the identifying the draft input by the user may specifically be identifying the draft on the operation interface saved in the screenshot. Specifically, the screenshot of the operation interface may be recognized by using a pre-trained region recognition model to recognize the operation interface region, after the operation interface region is recognized, the character content in the operation interface region may be recognized by using the character recognition model, during the recognition, each component in the operation interface region is marked, where the component may include a calculation question (title), a draft and an answer, and then the text content of the calculation question (title), the draft and the answer may be recognized by using the character recognition model. As shown in fig. 2, the calculation questions (titles) are identified as "16-9 + 5" and the draft is "7 + 5" by the region recognition model and the character recognition model.
Optionally, the determining whether each calculation step of the draft input by the user is correct includes:
generating a standard problem solving step according to a problem solving rule corresponding to the calculation problem; and
and judging whether each calculation step of the draft is correct or not according to the standard problem solving step.
In the process of judging whether each calculation step of the draft is correct according to the standard problem solving steps, if one calculation step corresponding to one of the standard problem solving steps is lacked in the draft, the next step of the standard problem solving steps is automatically skipped, and whether the calculation step corresponding to the step in the draft is correct is judged.
Preferably, if there is an error in the calculation step, the correct calculation step is displayed at the same time when the error is marked (i.e. the error is marked, for example, in the form of a cross, a red mark, etc.). Therefore, the arrangement is convenient for users to find problems in calculation, and the optimal exercise effect is achieved.
Preferably, the step of obtaining the problem solving rule includes: identifying the type of the computational problem; and selecting a corresponding problem solving rule according to the type of the calculation problem.
Here, the types of the calculation questions are mainly classified according to the form characteristics (for example, the number of unknowns, the power of several orders, the position, and the operation sign) of the questions of the calculation questions.
For example, if the identified calculation is subject toDetermining the form characteristic of the calculation question as a unary linear equation with denominator on a preset gaugeThen, a problem solving rule of a unary linear equation with denominator is selected from the library, and the selected problem solving rule can be: the method sequentially comprises five calculation steps of denominator removal, bracket removal, item shifting, homogeneous item combination and factorization to be 1, and then the following standard problem solving steps can be generated according to a problem solving rule comprising the five steps:
1. removing denominators to obtain: 5(x +4) ═ 3(x + 5);
2. removing brackets to obtain: 5x +20 ═ 3x + 15;
3. item shifting to obtain: 5x-3x ═ 15-20;
4. combining the same items to obtain: 2 ═ 5;
5. the coefficient is 1, and then:
it is noted that, as is well known, in the above example of generating the standard solution step, the calculating step of the denominator is generally to multiply both sides of the equation by the least common multiple of the two denominators (e.g., the least common multiple of denominators 3 and 5 is 15 in the above example). If the denominator is a fraction (including a decimal), the step of de-denominating may comprise two sub-steps: the fraction in the denominator is eliminated (e.g., the numerator and denominator can be multiplied by the reciprocal of the denominator), and then both sides of the equation are multiplied by the least common multiple of the two denominators.
By the equationFor example, the following steps are carried out: eliminating fractions in the denominator, i.e. the numerator and denominator on the left of the equation multiplied by the inverse of the denominator on the left of the equation 5, respectively, and the numerator and denominator on the right of the equation multiplied by the inverse of the denominator on the right of the equationCan change the equation intoThen, both sides of the equation are multiplied by the least common multiple 3 of the two denominators, and then the equation becomes: 15x is 4(x +1),the result of the calculating step of the depuncturing in the standard solving step of the above example is thus obtained.
In this embodiment, the type of the calculation problem may be identified by a pre-trained classification and recognition model, where the classification and recognition model may be a neural network model, and further may be a convolutional neural network model or a residual error network model, and the training process may specifically include the following steps:
preparing a certain number of picture samples marked with corresponding calculation question types for preset calculation question (question) types, wherein the number of the pictures of each calculation question type can be equal or different;
selecting a certain proportion of picture samples from the marked picture samples as a test set, wherein the selection can be manual or automatic random, the proportion is generally 5 to 20 percent (of the total picture samples), the proportion of the test set in the total picture samples can be adjusted according to results, and the rest picture samples are training sets;
training the classified recognition model by using the training set, and verifying the accuracy of the classified recognition model after the training of the training set is completed by using the test set;
